01' the operating mechanism is positively positioned in a predetermined position for one direction of its movement.

Another object is to provide a. combination lock wherein the combination is exactly determined for controlling the operating mechanism of the lock in one direction of rotation only. Unauthorized operation, or movement in an unpredetermined direction, serves to render the operation of the combination impossible.

Still another object is to provide a combination lock wherein maze members are provided per- 'mittlng operation of certain forms of the lock regardless of the position of the mechanism. while other forms of the lock are susceptible of operation through substantially 179.

Yet another object is to provide a combination lock wherein the maze is substantially trackless for certain movement of an operating element.

A further object is to provide a sightless combination lock susceptible of immediately posicombination lock which depends upon the touch tioning the lock at zero position, and wherein the operation may be effected through the sense of sound or feeling.

A still further object is to provide a sightless in the specification, drawings and claims appended hereto.

' same being taken substantially in thevplane indi- V is shown as applied, for-example, to a cabinet. In this construction the lock 2| is fixedly supported, preferably on a movable part 22 of a. cabinet adjacent a stationary part 24 of said cabinet in such a position that when 'fully locked the striker or locking member 26 ofthe lock will overlap a portion of the stationary member 24 to prevent movement of the movable member 22 toward the left 'or to open position as viewed in Figuresl,3and9., I

The lock consists essentially of the casing 2! provided at one end with the shoulder 30 providing a backing or engaging means for the plate 32 which is' adaptedto be disposed between said shoulder andthe member 22. A portion of the casing is threaded as at 34 for receiving fastening means such asthe nut 36, which is adapted to position the lock when applied to said threaded portion 34.1 A plate 38 is preferably disposed between the member 22 and the nut 36. Thecasing of the look, when in applied position extends beyond the nut ii, and is provided with the spaced shoulders or stops 40 and 42 adapted to provide limiting means for the stop 44 provided on the striker 26, whereby the striker can only be moved a predetermined amount, which in the construction shown is 90".

The casing is provided with the elongated aperture 46 extending therethrough and terminating at the operating end of thelock in a shouldered portion -4l, said shouldered portion being provided with the slot 52 in substantial align-' ment with the stop 40. The revoluble member 52 extends through the elongated aperture 46, being rotatably mounted in the casing, said revoluble member being provided with the flange 54 rotatably mounted on the shoulder portion 48, said member extending through the casing, and being provided with the elongated aperture 56 terminating adjacent .the inner end thereof with the threaded portion 58. The striker 26 is mounted on the projection ill and is retained in place by thetrack member or maze 52, said member having an inwardly projecting threaded portion 64 adapted to be received by the threaded portion 58, and when said track member is secured in its innermost position it overlaps and forms a securing means for the striker.

The opposite end of the revoluble member is recessed as at 66, and the shaft 68 extends through the recess and is revolubly mounted with respect to the revolvable member 52 and the maze 62, extending beyond said maze. The shaft is provided at one end with the operating member III, which may conveniently take the form of a knob, aportion of the operating member being journalled in the casing-3|. The opp site end of'the shaft is provided with the shoulder 12, and the planetrack memb'enouter track, race or disc I4 is non-rotatably mounted on the end of the shaft as at 16, said track member being preferably provided with a flange II extending toward the track member 62,.and an operating or spacing member such as the ball "isbetweenthetrackmembersfl and 14. The flange II is provided with the cut-' out or notched porflons 22 adapted to have cooperative eat with the pin 84 provided on thestrikeraothatwhmthe pin Misreceived inthe notches II the operating member licanpositively-turnthestriker.

' when received in said slot and notch the revo- .minating in a depression 84 adapted to receive,

the ball and permit the operating member III, the shaft 68 and the track member 14 to move toward the left as viewed in Figure 3, to a position wherein the pin 84 may be received in the slot 82, at which position the pin 90 is withdrawn fromthe slot the striker. l 7

Any movement from the fully locked position 50 to permit movement of causes thepin 9|) to be placed above the shouldered portion 48 of the casing, such as shown in Figure 7, whereby it will" be impossible to move the operating member, the shaft and race 14 toward the right or toward zeroized position as viewed in said figure, until the lock is returned to fully locked position. When the lock isreturned to fullylocked position, bodily movement, or .movement of translation of the shaft ill toward the right causes the shoulder," to

move the ball out of the depression where,

it will immediately fall to its lowermost or zero position, after which it will be necessary to operate the lock in its set or predetermined combination before it can be again unlocked.

During operation of the lock, in the event a The inner mistake is made in the combination, it can be immediately zeroized by moving the operating member-toward the right as viewed in said figure, releasing the frictional engagement between the ball and the tracks which permits the ball to fall to its lowermost or zero position.

As stated above, the lock shownis adaptedto operate on a 354 combination. The trackor maze 62' as viewed from a zero and fully locked position shown in Figure 4, is provided with the first track 96, a second track 96 extending inwardly a suilicient distance to accommodate the outermost path of the ball and its second path of movement. The third track 98 is adapted "to receive the ball and as the lock is set for a movement of the shaft in a counterclockwise direction as viewed in Figure 4, if the movement is reversed, that is, to a clockwise direction, the ball will move inwardly to the apex of the track 88. Reversal of the'shaft to again rotate thedisc 14 in a counterclockwise direction causes the ball 'to move over tracks Hill to the lock shown it is impossible with track portion Ill to count from zero to ei ht and'operate through the second path of movement. Again reversingthemovementoftbediscllorsbaft ea s 3 II at the track I02 causes .the ball to move insubstantially spherical or oi similar formation, wardly to its third path of movement, whereupon the outer track ill fastened to the shait 68 as at the shaft 88 and disc 14 are again moved in I! being correspondingly 'i'o a counterclockwise direction to move the ball A diiierent iorm oi construction is illustrated i in its third path or movement over the track in Figures 13, 14 and 15.
